Is there a way to pass in Rest Services endpoint info via the command line (mvn) ?

1. soapui project changes: You may set a project level property say APPLICATION_URL and update the test requests with endpoint as ${#Project#APPLICATION_URL}
2. pom.xml changes:

    <plugin>
        <groupId>com.smartbear.soapui</groupId>
        <artifactId>soapui-maven-plugin</artifactId>
        <version>4.6.1</version>
        <configuration>
            <systemProperties>
              <property>
                 <name>endpoint</name>
                 <value>${app.url}</value>
              </property>
            </systemProperties>
            <projectFile>simple-test-soapui-project.xml</projectFile>
            <projectProperties>
                <value>APPLICATION_URL=${app.url}</value>
            </projectProperties>
        </configuration>
    </plugin>

Now, you may add -Dendpoint=http://yourhost:port your command

Disclaimer: Just collected it from net, never tried myself.
